Abstract

The present application relates to a camera calibration method, device, computer equipment and storage medium. The calibration method of the camera includes: obtaining a reference image obtained by collecting a calibration feature of a calibration target captured by a reference camera, and extracting reference feature information of the calibration feature mapped in the reference image; The calibration image obtained by the calibration feature, and extracting the calibration feature information of the calibration feature mapped in the calibration image; determining the reference camera and the camera to be calibrated according to the reference feature information and the calibration feature information Calibrate the camera to be calibrated according to the reference calibration information of the reference camera and the calibration mapping relationship to obtain target calibration information of the camera to be calibrated. The calibration method of the camera can improve the calibration efficiency of the camera.

Description

technical field [0001] The present application relates to the technical field of computer vision, in particular to a camera calibration method, device, computer equipment and storage medium. Background technique [0002] With the development of computer vision technology, there has been a technology that uses computer vision for automatic alignment and bonding. Alignment fitting is realized by using the images obtained by taking pictures up and down. In the process of aligning and fitting, the calibration of the upper and lower cameras is a very important prerequisite. [0003] At present, the commonly used calibration method is usually to automatically calibrate the lower camera using the motion axis, and then calibrate the camera through a specific calibration paper or use a high-precision caliper to complete the calibration of the upper and lower cameras. [0004] However, when the camera is calibrated through a specific calibration paper or using a high-precision calip...
